SPECIFICATION forming part of Letters Patent No. 761,301, dated May 31,1904.

Application filed J111y'2,'19 01.

To all. whom it may concern: 1

Be it knownthat I, ARTHUR J EFFERY, a subject of the King of England,and a resident of Muster Green, Haywards Heath, Sussex, England, haveinvented certain new and useful 1mprovements in Apparatus for Meltingand Distributing Adhesives; and I do hereby declare .the following is afull and clear description thereof.

This invention relates to an improved apparatus for melting anddistributing adhesive substances.

The apparatus consists of a rectangular-' shaped vessel, in which thematerial to be melted is placed. This vessel is open at the top, and thebottom is made sloping, flat in shape at one end and semicircular at theother. A series of heating-tubes are located at or near the lower partof the same. fits into another vessel sufficiently large to allow aspace all around the said vessel and extending to about half the heightof the said inner vessel and is so constructed as to form a spaceall-over the lower part of the inner vessel, so that a heating-eharnberis provided for the outside of thelower part of the inner vessel as wellas through the tubes aforesaid.

The heat is provided by a any convenient meansas, for instance, the heatof a lamp attached to one end of the outer vessel, the heated air thusgenerated passing through an opening provided in the outer casing. Aportion of this heated air circulates around the lower part of the innervessel, and the remaining portion goes through the tubes, so that a.

large amount of heating-surface isby this means provided for the purposeof heating and melting the glue or other similar substance. The oppositeend to that to which the lamp is fixed is perforated with holes, and abaffle-plate for the'escape of the heated gas is provided, and alsoabranch or outlet pipe of convenient diameter is provided at the bottomof the outer vessel for the escape of the heated gas. An outlet branchpipe is provided at the lower end of the inner vessel, which leads downinto the outlet-pipe of the outer vessel and terminates in a valve soconstructed that when moved it controls the flow of melted glue bycovering the end of the branch pipe from The said vessel I partly inelevation.

the melting-pot or inner vessel. The wholeapparatus may be mounted on acarriage with V-edge wheels which may be made to run in the seams of thefloors or decks, and thereby guide the apparatus so that the end of thebranch outlet may be exactly over the seam to be filled with thesubstance. The flow of the liquid glue may be regulated by means of alever and handle attached to the carriage in any convenient manner. Theglue or substance to be melted is placed in the inner vessel, as beforementioned, which becomes heated by the gas generated by the lamp, andthe melted substance flows down the sides of or through the tubes intothe lower part of the vessel and down into the branch pipe, itsliquid-state being uniformly maintained till it is led into the seams ofthe floor.

In order that this invention may be readily understood, reference ismade to the accompanying drawings, in which Figure 1 represents a sideelevation of the apparatus. Fig.2 is a vertical sectional view, Fig. 3is a transverse sectional view. Fig. 4 is a horizontal sectional View ofa modified form of the melting-pot detached from the machine, and Fig.'5 is a vertical sectional view of the same. Fig. 6 is a verticalsectional detail showing a series of tapering tubes as distinguishedfrom the vertical cylindrical tubes illustrated in Fig. 5.

The same numerals refer to the same parts in the several views, 1 beingthe melting-pot or rectangular-shaped vessel, which is open at the top2, and the bottom 3 is preferably made sloping and semicircular.lrepresents tubes running from back to front of the said vessel.

5 is the outer vessel, of a size to allow of air-space at the sides andends of the vessel for the convenient passing of the heated air or gasthrough the apparatus.

6 represents Vent-holes in the sides and end of the outer vessel 5;

7.represents baffle-plates for regulating the heat.

8 is a branch pipe or semicircular opening for receiving the funnel orchimney of the lamp 9.

10 is the outlet-tube, preferably tapering in diameter, for conveyingthe melted substance to the outlet-valve 11. iVhen the valve is open,the liquid glue flows out through the tube and into the seams of thefloor or deck or where it is desired to be conveyed. The action of thevalve 11 is regulated by the wire rod 12, passing through the valve-tubeto a pivoted lever 13, which in turn is pivoted to a rod 14, having ahandle 15, sliding upon the handle-bar 16, controlled by the operatorwho is using the apparatus.

The whole apparatus is mounted on a carriage-frame 17, having wheels 18with tapered peripheries 19, which are placed at an angle forconveniently running in the seams of the deck or floor.

The heated-gas generated by the lamp 9 passes partly through the tubes 4and partly around the vessel and escapes either through the vent-hole 6or through the outer tube 20, surrounding the delivery-pipe 10. A largeamount of heating-surface is by this means provided, efiectually heatingand melting the glue in the vessel. The glue lies on the tubes 4 and isgradually melted, flowing down the sides of and between the said tubesto the valve 11, the liquid state of the substance treated beinguniformly maintained till it reaches the seams of the deck or floor orplace to which it is directed.

I prefer to have the inclined beveled wheels 18 upon one side of theapparatus only. The

opposite wheels 21 are vertically arranged.

The object of inclining the wheels 18 is to permit the machine to be runvery close to any raised portion of the deck or next to a vertical Wallwithout coming in contact therewith. In the modification shown in Figs.4 and 5 the melted glue flows through the vertical tubes 22 instead ofaround the same, as in Figs. 1 and 3, the products of combustion passingbetween the horizontal walls 23 and 24. Fig. 6 is the same constructionas Figs. 4 and 5, except that the vertical tubes 25 are tapered insteadof being cylindrical.

In the modification shown in Figs. 4 and 5 the flame of the lamp 9 ispreferably directed against the beveled plate 26 and some of thevertical tubes nearest the flame are omitted at the points 27 in orderto more uniformly equalize the temperature and prevent the overheatingof the tubes nearest the flame.

When the glue is placed on top of the tubes 4, 22-, and 25 and heatapplied through the exterior heating-chamber 5, it will be noted thatthe glue is melted only at the bottom of the vessel 1 and graduallydrips down either around or through the tubes into the deliverytube 10and through the valve 11. A portion of the heat is deflected downwardlythrough the tubular casing 20, keeping the dischargespout and the valveat a sufficiently high temperature to maintain the glue in its liquidcondition until after it is deposited in the seams of the floor or otherpoints. I

This apparatus-for applying glue is highly desirable, for the reasonthat there is always a charge or magazine of unmelted glue which isautomatically fed to the liquidation-point in the furnace, as required,without further attention. At the same time the fluidity of the glue. ismaintained through the conveying-pipes and the discharge-valve. Afterbeing charged with glue the device is at all times ready for use bysimply lighting the lamp, the result being that the glue which hadpreviously cooled in the valve and discharge-pipe and lower end of thefurnace is liquefied and the valve 11 rendered operative without anyfurther attention. By this means the decks and floors may be readilyrepaired at any time. For keeping the decks of vessels and other floorsexposed to the weather in proper condition this apparatus has proveditself to be highly desirable and successful.

What I claim as new, and desire to secure by Letters Patent, is

1. In a paying apparatus, for floors and decks, the combination of amovable ad hesiveeontaining vessel having a melting-compartmentbelow thesame, and provided with means for supporting the solid adhesive abovethe melting-compartment, means for introducing heat to themelting-compartment and means for delivering the melted adhesive to thefloor.
